Hypoxic training for Masters?

Thanks for the link; although disputing the adaptations we've mentioned, the article did not at all seem "anti-hypoxic" in nature. The whole "athletes can swim faster with more oxygen" of course ignores underwater SDK, which is faster than most surface swimming and is my own reason for any hypoxic training I do. In fact, I was pleased to see that Austin Staab seems to approach his underwater training similarly to me with his whole "at least 7 kicks off every wall" to build underwater endurance. His interview is here. Pretty incredible that he could do the last 25 of his 100 fly without a breath. I agree the article I cited was not anti-hypoxic. It was a bit dated (2003) and mentioned Counsilman's view. But it didn't provide any evidence that hypoxic training actually worked. Maglischo suggests that it doesn't work as claimed, and perhaps not at all. As for SDK - that is not an oxygen issue at all. It is a hydrodynamic issue. The evidence clearly shows that swimming underwater can be faster than swimming on the surface. Maglischo wasn't saying don't swim underwater. He was just saying that when you're swimming - it is probably better to swim faster with breathing than swimming slower with less breathing.
